SWAIN WINKLEY, OF NEW YORK, N. Y.

IMPROVEM ENT IN RAILWAYS.

Specification forming part of Letters Patent No. 59,112, dated October 23, 1866.

1o all whom it may concern.-

Be it known that I, SWAIN WINKLEY, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Railways; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification7 and to the letters of reference marked thereon.

My invention relates to the construction of railways with corrugated-iron base-plates for the support of the rails, such as have been heretofore invented by me 5 and it consists of an improved construction of the same, by which the plates are arched in the direction of the corrugations. The plates are composed of a series of corrugations, tied or held together by a cappiece, upon which the rails rest; and the corrugations or ribs are deeper and thicker at the center, Where they sustain the most strain, than at the edges, where the strain is least. The cross-ties are fitted at each end with a locking-piece, that clasps the cap of the base-plate and the foot of the rail, and is wedged with a key that secures the whole together. v

To enable others skilled in the art to which it appertains to make and use my invention, I will proceed to describe its construction and operation with reference to the drawings.

Figure l is a transverse View of a road showing a pair ot' baseplates, with one side in section. Fig. 2 is a plan of one of the baseplates, and Fig. 3 is an end view of the same. Fig. 4 is a sketch of the end of a tie, with its locking-piece and key.

The base-plates a are corrugated in one direction and arched in the other, andare furnishedwith the cap b, upon which the rails rest, with felt or india-rubber interposed, if necessary. The pairs of plates are connected by the cross-ties c and the clasps d, that are securely fastened by the taper split key e.

I do not claim the application of corrugated iron to the construction of railways, nor do I here claim the construction of corrugated bascplates with a strengthening-tie or cappiee across the corrugations. I claim- The construction of the base-plates with arched corrugations, as described.
